Considering the role of the personal story in GW2, I think it would be interesting if there were similar scenarios set in place for groups. Developers could implement a set of events/questions similar to that of character creation, but a party must agree on the settings.
This story could be advanced as long as two members of the original party is present, and could span over any amount of time, similar to the personal story now, and would create a kind of legacy for you and your friends.
For example, a team could come out with the quest of tracking a creature that they designed through a series of questions, and that quest could take them all over the map, or just one dungeon.
There are a ton of ideas that could be implemented in this system, and it is a good way to get guilds to play together. A system like this can also offer something for people who are more interested in role playing scenarios than the current PvE content.
